It is an object of the present invention to provide novel herbicidal substances.

We have found that this object is achieved by the carboxamides Ia, Ib and Ic defined at the outset and processes for their preparation.

We have also found that the carboxamides Ia, Ib and Ic as well as the carboxamides IA, IB and IC are suitable for controlling undesirable plant growth.

The novel carboxamides Ia, Ib and Ic can be prepared by various methods. They are obtained, for example, by the following processes.

1. Process for the preparation of the compounds Ia in which R⁵ is carboxyl: ##STR10## These carboxamides are obtained by converting a corresponding dicarboxylic anhydride of formula II in a conventional manner into an amine of the formula III. ##STR11##

The action is carried out, as a rule, at from -10° to 100° C., preferably from 0° to 30° C., in an inert organic solvent.

Suitable solvents are ethers, such as methyl tert-butyl ether, 1,2-dimethoxyethane, diethylene glycol dimethyl ether, tetrahydrofuran and dioxane.

The concentration of the educts in the solvent is is general from 0.1 to 5, preferably from 0.2 to 2, mol/l.

The molar ratio of II to III is in general from 1:5 to 1:1, preferably from 1:2 to 1:1.

The required dicarboxylic anhydrides II are known or can be prepared in a conventional manner by reacting the corresponding dicarboxylic acids with the anhydride of a lower carboxylic acid, in particular acetic anhydride.

2. Process for the preparation of the compounds Ia, Ib and Ic in which R³ and R⁴ are not bromine or iodine and R⁵ is formyl or carboxyl: ##STR12##

These compounds Ia, Ib and Ic are obtained by converting a corresponding carboxylic acid of the formula IVa, IVb or IVc in a conventional manner into the halide or another activated form of the carboxylic acid, then reacting these derivatives with an amine of the formula III and thereafter reacting the resulting carboxamide Va, Vb or Vc with a formylating or carboxylating reagent in the presence of a base. ##STR13##

The individual reaction steps of this synthesis sequence can be carried out in general as follows:

Reaction step A:

The compounds Va, Vb or Vc are obtained from the acids IVa, IVb and IVc by first converting IVa, IVb or IVc in a conventional manner into the halide or another activated form of the carboxylic acid function and then amidating these derivatives with an amine III.

In addition to halides, in particular the chlorides and the bromides, other activated forms of the carboxylic acid are, for example, imidazolides. In general, the halides are preferred.

They are obtained by reacting the carboxylic acids IVa, IVb or IVc with an halogenating agent, such as thionyl chloride, thionyl bromide, phosphorus oxychloride or -bromide, phosphorus tri- and pentachloride or -bromide, phosgene and elemental chlorine and bromine.

The halogenating agent is used in an amount of from 1 to 5, preferably from 1 to 2, mole equivalents.

The reaction takes place at from 20° C. to the boiling point of the halogenating agent or, if the reaction is carried out in the presence of an inert organic solvent, to the boiling point of the latter.

Examples of suitable solvents are hydrocarbons and halohydrocarbons, such as benzene, toluene and dichloromethane.

The activated carboxylic acid derivatives are usually isolated, for example by distilling off the halogenating agent and, where present, the solvent, before being reacted with the amines III.

In this case, the amidation is carried out at from -20° to 50° C., preferably from 0° to 30° C., in an inert aprotic polar organic solvent.

Halohydrocarbons, such as dichloromethane and ethers, such as diethyl ether and tert-butyl methyl ether, are particularly suitable solvents for this reaction.

Since hydrogen halide is formed in the amidation of acyl halides, it is advisable to add the amine III in an excess of from 2 to 5 and preferably 2 to 3, mole equivalents. If the amine is used in equimolar amounts (from 1 to 1.2 mole equivalents), a base, in particular a tertiary amine, such as triethylamine or pyridine, should be added to bind the hydrogen halide.

Reaction step B:

The formylation or carboxylation of the carboxamides Va or Vb or Vc is carried out, as a rule, at from -100° to -20° C., preferably from -80° to -40° C., in an aprotic polar inert organic solvent in the absence of moisture and in the presence of a base.

In particular, dimethylformamide and N-formylmorpholine are used as formylating reagents, a preferred carboxylating agent being carbon dioxide.

Particularly suitable solvents are diethyl ether, tert-butyl methyl ether, tetrahydrofuran and dioxane.

Preferably used bases are alkali metal hydrocarbons, such as methyllithium, n-butyllithium, tert-butyllithium and phenyllithium.

The reaction is usually carried out in such a way that from 1.3 to 2.5 mole equivalents of the dissolved base are first added to the carboxamide Va or Vb to give a carboxamide derivative which is metalized in the ring, said derivative reacting to give the desired product Ia, Ib or Ic on subsequent addition of the electrophilic formylating or carboxylating reagent.

Since, where R¹ or R² is H, the first mole equivalent base merely deprotonates the amide nitrogen, in this case less than 2 mole equivalents of base are required to metalize the heterocycle; in this case, the reaction is preferably carried out in the presence of from 2 to 2.5 mole equivalents of the base.

The carboxylic acids IVa, IVb and IVc required for this process are known from the literature or can be prepared by general methods known from the literature, for example by oxidation of the corresponding alcohols or aldehydes or by hydrolysis of the corresponding nitriles (Beilstein, main section and 1st to 5th supplements, Volume 18 , The Chemistry of Heterocyclic Compounds, Interscience Publishers, New York, 1976, John Wiley & Sons, Inc., 1988, Vol. 44, Part I-III).

3. Process for the preparation of the compounds Ib and Ic in which R³ or R⁴ is halogen, R⁵ is CO₂ R⁶ and R⁶ is alkyl: ##STR14##

These compounds Ib and Ic are obtained by a method in which a dicarboxylic diester of the general formula VIa or VIb is first diazotized in a conventional manner and the diazotized compound is converted with an inorganic halide into the corresponding derivative VIIa or VIIb, VIIa or VIIb is then amidated with an amine of the formula III and the resulting mixture of the isomeric compounds Ib and Ic is separated into the individual components. ##STR15##

In formulae VIIa, VIIb, Ib and Ic, Hal is halogen, such as fluorine, chlorine, bromine or iodine.

The reaction steps of this synthesis sequence can be carried out in general as follows:

Reaction step A:

The diazotization of the dicarboxylic ester of the general formula VIa or IVb is carried out, as a rule, at from -20° to +20° C., preferably from -5° to +10° C., in a mineral acid, in particular hydrochloric acid, in the presence of an alkali metal nitrite, such as sodium nitrite.

The diazonium salt thus obtained is then reacted in situ with from 1 to 5, preferably from 1.5 to 2.5, moles of an inorganic halide, in particular a copper (I) halide.

The reaction conditions may be varied within the limits of the processes known for the Sandmeyer reaction (also see Houben-Weyl, Vol. X/3, pages 1-212 (1965); Chem. Zvesti 36 (1982), 401).

Reaction step B:

The reaction of the resulting dicarboxylic ester VIIa and VIIb with the amine III is carried out in general and in particular under conditions similar to those described in process 1.

However, solvents used in particular here are halohydrocarbons, such as methylene chloride, and ethers, such as diethyl ether, tert-butyl methyl ether and tetrahydrofuran.

The amine III is generally used in equimolar amounts or in excess, preferably in amounts of from 1 to 1.2 mole equivalents, based on VIIa or VIIb.

This process gives the isomeric carboxamides of the formulae Ib or Ic in different amounts. The isomeric mixture is separated either by fractional crystallization or by a chromatographic method.

Dicarboxylic diesters VIa and VIb required for this process are known or can be prepared from the corresponding oxo esters Xa, for example under conditions similar to those described in Synthesis, 1977, 200, in accordance with the following reaction scheme: ##STR16##

4. Process for the preparation of the compounds Ib and Ic in which R⁵ is carboxyl: ##STR17##

These carboxamides Ib and Ic are obtained, for example, by hydrolyzing a corresponding carboxamide of the formula Ib or Ic where R⁵ is CO₂ R⁶ and R⁶ is alkyl in a conventional manner with an aqueous base. ##STR18##

The reaction is carried out by a method in which a carboxamide Ib or Ic (R⁶ =alkyl) in an inert solvent is initially taken and is reacted with an aqueous base at from -30° to 120° C., preferably from -10° to 40° C. The carboxamides of the formula Ib or Ic (R⁵ =CO₂ H) are then liberated at from -30° to 100° C., preferably from -10° to 10° C., by adding mineral acids.

Suitable solvents for this ester cleavage are alcohols, such as methanol, ethanol, propanol or ethylene glycol; the reaction is particularly preferably carried out in the alcohol corresponding to the ester component R⁶ OH. The concentration of the educt Ib or Ic is in general from 0.1 to 5.0, preferably from 0.2 to 2.0, mole/l.

Solutions of alkali metal or alkaline earth metal hydroxides, such as LiOH, NaOH, KOH, Ca(OH)₂ or Ba(OH)₂, preferably NaOH or KOH, are used as the aqueous base. The hydroxides are used in the form of a 5-20% strength aqueous solution.

The molar ratios in which esters Ib and Ic and hydroxides are used are from 1:0.95 to 1:1 for alkali metal hydroxides and from 1:0.48 to 1:0.55 for alkaline earth metal hydroxides.

5. Process for the preparation of the compounds Ia, Ib and Ic in which R⁵ is COYR⁶ : ##STR19##

These compounds are obtained, for example, if a carboxamide Ia, Ib or Ic in which R⁵ is CO₂ H is converted in a conventional manner into or an activated form of the carboxylic acid, and these derivatives are then esterified with a compound VIII. ##STR20## This reaction is usually carried out at from -20° to 60° C., preferably from 0° to 40° C.

Advantageously used solvents are halohydrocarbons, such as chlorobenzene and 1,2-dichlorobenzene, ethers, e.g. methyl tert-butyl ether, 1,2-dimethoxyethane, diethylene glycol dimethyl ether, tetrahydrofuran and dioxane, dipolar aprotic solvents, e.g. acetonitrile, dimethylformamide, dimethylacetamide, dimethyl sulfoxide, N-methylpyrrolidone, 1,3-dimethyltetrahydro-2(1H)-pyrimidinone and 1,3-dimethylimidazolin-2-one, or aromatics, e.g. benzene, toluene and xylene. The concentration of the educts in the solvent is in general from 0.1 to 5.0, preferably from 0.2 to 2.0, mole/l.

As a rule, from 1 to 1.5, preferably from 1 to 1.15, mole equivalents, based on the carboxylic acid Ia, Ib or Ic (R⁵ =CO₂ H), of the compound V are used.

Suitable dehydrating agents are diimides, such as dicyclohexylcarbodiimide (also see Angew. Chem. 90 (1978), 556) or anhydrides, such as propanephosphonic anhydride. The reaction also takes place in the presence of 1-methyl-2-halopyridinium iodides as dehydrating agents (cf. Chem. Lett., 1045 (1975); ibid., 13 (1976); ibid., 49 (1976)).

The reaction is particularly preferably carried out in an inert solvent, such as tetrahydrofuran, dichloromethane or toluene, in the presence of dicyclohexylcarbodiimide as a dehydrating agent with the use of the carboxylic acid I, the compound IV and the dehydrating agent in stoichiometric amounts at from 20° to 40° C.

The reaction is complete in general after 14 hours; the carboxamides Ia, Ib and Ic are isolated in a conventional manner (for example by diluting the reaction mixture with water and extracting the product with an organic solvent) and are purified by conventional standard methods, such as recrystallization or chromatography.

6. Process for the preparation of the compounds Ia, Ib and Ic in which R⁵ is 4,5-dihydrooxazol-2-yl: ##STR21##

These compounds Ia, Ib and Ic are obtained, for example, by subjecting a corresponding dicarboxamide from Ia, Ib or Ic where R⁵ is carboxyl to a cyclization reaction with 2-aminoethanol IX in a conventional manner. For the sake of clarity, this reaction is described below using a typical example for the compounds Ia. ##STR22##

The reaction is carried out by a method in which the compounds are reacted with an amino alcohol IX in the presence or absence of an inert solvent at from 0° to 180° C., preferably at the reflux temperature of the mixture used. The ester or carboxylic acid Ia, Ib or Ic and amino alcohol IX are used in a ratio of from 1:1 to 1:2.5, preferably from 1:1 to 1:1.5.

Advantageously used solvents are halohydrocarbons, such as chlorobenzene and 1,2-dichlorobenzene, ethers, e.g. methyl tert-butyl ether, 1,2-dimethoxyethane, diethylene glycol dimethyl ether, tetrahydrofuran and dioxane; alcohols, such as methanol, ethanol, propanol or ethylene glycol, dipolar aprotic solvents, e.g. acetonitrile, dimethylformamide, dimethylacetamide, dimethyl sulfoxide, N-methylpyrrolidone, 1,3-dimethyltetrahydro-2(1H)-pyrimidinone and 1,3-dimethylimidazolin-2-one, or aromatics, e.g. benzene, toluene and xylene. The concentration of the educts in the solvents is in general from 0.1 to 5.0, preferably from 0.2 to 2.0, mole/1.

The reaction is complete in general after 14 hours; the carboxamides Ia and Ib are, if required, then precipitated by the addition of water, filtered off under suction or extracted with an organic solvent and purified by conventional standard methods, such as recrystallization or chromatography.

Suitable salts of compounds of the formula IA, IB and IC are agriculturally useful salts, for example alkali metal salts, such as the potassium or sodium salt, alkaline earth metal salts, such as the calcium, magnesium or barium salt, manganese, copper, zinc or iron salts, and ammonium, phosphonium, sulfonium or sulfoxonium salts, e.g., ammonium salts, tetraalkylammonium salts, benzyltrialkylammonium salts, trialkylsulfonium salts and trialkylsulfoxonium salts.

The herbicidal compounds IA, IB and IC according to the invention, or herbicidal agents containing them, may be applied for instance in the form of directly sprayable solutions, powders, suspensions (including high-percentage aqueous, oily or other suspensions), dispersions, emulsions, oil dispersions, pastes, dusts, broadcasting agents, or granules by spraying, atomizing, dusting, broadcasting or watering. The forms of application depend entirely on the purpose for which the agents are being used, but they must ensure as fine a distribution of the active ingredients according to the invention as possible.

For the preparation of solutions, emulsions, pastes and oil dispersions to be sprayed direct, mineral oil fractions of medium to high boiling point, such as kerosene or diesel oil, further coal-tar oils, and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons such as toluene, xylene, paraffin, tetrahydronaphthalene, alkylated naphthalenes and their derivatives, methanol, ethanol, propanol, butanol, cyclohexanol, cyclohexanone, chlorobenzene, isophorone, etc., and strongly polar solvents such as N,N-dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone, water, etc. are suitable.

Aqueous formulations may be prepared from emulsion concentrates, pastes, oil dispersions, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes and oil dispersions the ingredients as such or dissolved in an oil or solvent may be homogenized in water by means of wetting or dispersing agents, adherents or emulsifiers. Concentrates which are suitable for dilution with water may be prepared from active ingredient, wetting agent, adherent, emulsifying or dispersing agent and possibly solvent or oil.

Examples of surfactants are: alkali metal, alkaline earth metal and ammonium salts of aromatic sulfonic acids, e.g., ligninsulfonic acid, phenolsulfonic acid, naphthalenesulfonic acid and dibutylnaphthalenesulfonic acid, and of fatty acids, alkyl and alkylaryl sulfonates, and alkyl, lauryl ether and fatty alcohol sulfates, and salts of sulfated hexadecanols, heptadecanols, and octadecanols, salts of fatty alcohol glycol ethers, condensation products of sulfonated naphthalene and naphthalene derivatives with formaldehyde, condensation products of naphthalene or naphthalenesulfonic acids with phenol and formaldehyde, polyoxyethylene octylphenol ethers, ethoxylated isooctylphenol, ethoxylated octylphenol and ethoxylated nonylphenol, alkylphenol polyglycol ethers, tributylphenyl polyglycol ethers, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers, ethoxylated polyoxypropylene, lauryl alcohol polyglycol ether acetal, sorbitol esters, lignin-sulfite waste liquors and methyl cellulose.

Powders, dusts and broadcasting agents may be prepared by mixing or grinding the active ingredients with a solid carrier.

Granules, e.g., coated, impregnated or homogeneous granules, may be prepared by bonding the active ingredients to solid carriers. Examples of solid carriers are mineral earths such as silicic acids, silica gels, silicates, talc, kaolin, attapulgus clay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground plastics, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, and ureas, and vegetable products such as grain meals, bark meal, wood meal, and nutshell meal, cellulosic powders, etc.

The active ingredients or the herbicidal agents containing them may be applied pre- or postemergence. If certain crop plants tolerate the active ingredients less well, application techniques may be used in which the herbicidal agents are sprayed from suitable equipment in such a manner that the leaves of sensitive crop plants are if possible not touched, and the agents reach the soil or the unwanted plants growing beneath the crop plants (post-directed, lay-by treatment).

When the active ingredients are used as herbicides, the application rates depend on the objective to be achieved, the time of the year, the plants to be combated and their growth stage, and are from 0.001 to 5, preferably 0.01 to 3, kg of active ingredient per hectare.

The application rates depend on the objective to be achieved, the time of the year, the plants to be combated and their growth stage, and are from 0.001 to 4, preferably 0.01 to 2, kg of active ingredient per hectare.

The herbicidal action of carboxamides of the formula IA, IB and IC is demonstrated in greenhouse experiments:

The vessels employed were plastic flowerpots having a volume of 300 cm³ and filled with a sandy loam containing about 3.0% humus. The seeds of the test plants were sown separately, according to species.

For the preemergence treatment, the active ingredients, suspended or emulsified in water, were applied to the surface of the soil immediately after the seeds had been sown. After the agents had been applied, the vessels were lightly sprinkler-irrigated to induce germination and growth. Transparent plastic covers were then placed on the vessels until the plants had taken root. The cover ensured uniform germination of the plants, insofar as this was not impaired by the active ingredients.

For the postemergence treatment, the plants were grown, depending on growth form, to a height of 3 to 15 cm before being treated with the compounds, suspended or emulsified in water. The application rates for post-emergence treatment were 0.5 and 1.0 kg/ha.

The pots were set up in the greenhouse, heat-loving species at 20° to 35° C., and species from moderate climates at 10° to 25° C. The experiments were run for from 2 to 4 weeks. During this period the plants were tended and their reactions to the various treatments assessed. The assessment scale was 0 to 100, 100 denoting nonemergence or complete destruction of at least the visible plant parts, and 0 denoting no damage or normal growth.

The plants used in the greenhouse experiments were Chenopodium album, Chrysanthemum coronarium, Euphorbia heterophylla, Galium aparine, Triticum aestivum, Hordeum vulgare, Polygonum persicaria, Sinapis alba, Matricaria inodora, Ipomoea spp. and Zea mays.

Active ingredients nos. 1.025, 2.003, 3.014, 3.019, 3.031 and 3.032, applied postemergence at rates of 0.5 and 1.0 kg/ha, provide excellent control of unwanted broadleaved plants. Active ingredients nos. 1.025 and 3.014 are also well tolerated by wheat.
